Announcement for Interlaboratory Comparison on POPs in Food 2018

Introduction We hereby announce the 19th round of the Interlaboratory Comparison on the Determination of POPs in Food (“The Norwegian POPs in Food-study”). The study is open for academic, regulatory as well as commercial laboratories world-wide. The organizer of this study is Department of Environmental Exposure and Epidemiology at the Norwegian Institute of Public Health, Oslo, Norway. The study is scheduled to take place from January to April 2018. A draft report will be available by mid-June 2018, and the final report will be available to the participants by October 2018. All participants who have contributed to the results will receive a certificate of participation in the study. Objectives One of the main objectives of this exercise is to assess the interlaboratory consistency in results from analyses of dioxins, PCBs, PBDEs and HBCDs in regular food items known to contribute to the intake in the general population. Further, the world-wide readiness and capacity in analysing halogenated persistent organic pollutants in food will be demonstrated. The study also serves as a tool of quality assurance for the participating laboratories. Participants We encourage all laboratories world-wide working in this field to participate and assess their analytical performance. To do this, participants are requested to completely fill out the Registration Form and mark the desired sample types and what analyte solutions they intend to determine. Analytical requirements In this interlaboratory comparison, all the seventeen 2, 3, 7, 8-substituted PCDDs and PCDFs, the four non-ortho PCBs, CB-77, 81, 126 and 169 as well as the eight mono-ortho PCBs, CB-105, 114, 118, 123, 156, 157, 167, and 189 will be assessed. In addition, the participants are invited to determine six marker PCBs, eight PBDEs and HBCDs. The concentration of the following congeners can be reported: CB-28, 52, 101, 138, 153 and 180 and BDE-28, 47, 99, 100, 153, 154, 183 and 209. The concentration of α-HBCD, β-HBCD and γ-HBCD as well as the total of these isomers will also be assessed. The test materials consist of three fresh food homogenates. You can choose to analyse one, two or all three of the food items. We encourage you to determine as many analytes as possible. You are further requested to determine and report the lipid content of the foods. We also include standard solutions of all analytes that should be analysed as solutions of known concentration, which may be used to check your own calibration solutions.

Test material The test materials consist of three unfortified natural food product homogenates:

• Reindeer meat (labelled “Reindeer meat-2018”) ~100 g • Salmon (labelled “Salmon-2018”) ~100 g • Fish oil (labelled “Fish oil-2018”) ~60 g

The samples will be distributed by an international courier service to the participating laboratories. Please note: In order to avoid delay or retention of the samples at customs, please inform us if there are import restrictions in your country for any of the samples. Instructions for analysis and reporting Further detailed instructions and reporting forms will be sent by e-mail simultaneously with the dispatch of the samples in January. In short, the participating laboratories should: • use their own standard operation procedures for extraction clean-up and instrumental

determination • use their own reference standards for identification and quantification • report one single concentration for each analyte in each food matrix determined on fresh

weight basis • report limits of detection for all measured analytes in each food item • report the lipid content Time schedule

Announcement December 2017

Instructions for participants

January 2018 1. Introduction This is the 19th Round of the Interlaboratory Comparison Study on the Determination of POPs in Food organised by the Department of Environmental Exposure and Epidemiology, Norwegian Institute of Public Health, Oslo, Norway. The objective of this exercise is to assess the interlaboratory comparability of the results from analyses of all dioxins and dioxin-like PCBs included in the WHO-TEF schemes in regular foods. Participants may also determine and report concentrations of six marker PCBs, eight polybrominated diphenylethers (PBDEs) and hexabromocyclododecane (HBCD). The exercise serves as a quality assurance instrument for the participating laboratories. A further purpose is to assess the world-wide readiness and capacity for the determination of dioxin-like compounds, marker PCBs, PBDEs and HBCD in food. Instructions for the analysis and submission of results are given below. Please read these instructions carefully before starting the experimental work. The participating laboratories will contribute to the interlaboratory comparability in the analytical performance for determination of • dioxins and furans: all seventeen 2,3,7,8-substituted PCDDs and PCDFs • non-ortho PCBs: CB-77, 81, 126 and 169 • mono-ortho PCBs: CB-105, 114, 118, 123, 156, 157, 167 and 189 • indicator PCBs: CB-28, 52, 101, 138, 153 and 180 • PBDEs: BDE-28, 47, 99, 100, 153, 154, 183 and 209 • HBCD α-HBCD, β-HBCD, γ-HBCD and total HBCD in the following samples: • Reindeer (Reindeer-2018) • Salmon (Salmon-2018) • Fish oil (Fish oil-2018)

3.3 Analytical procedure Storage of the samples The samples are fresh, frozen homogenates of natural food items. They are shipped frozen and should be stored frozen until they are analysed. Methods to be used Laboratories shall use • their own methods for sample preparation and instrumental analysis • their own internal- and quantification standards • their own lipid determination procedure Standard solutions The standard solutions should be analysed using the laboratory’s own quantification standards and methods and the results shall be reported. General Beware of the high risk of background contamination and positive blank values when analysing food samples with levels of dioxins, PCBs, PBDEs and HBCD in the low ppt range. Use sample size according to expected levels of dioxins for the determinations in order to achieve a detection level that leaves as few as possible analytes as non-detected. The sample amount dispatched is not meant for replicate analyses. The samples might become inhomogeneous during freezing and transport. Re-homogenise all received material of each food item before any portion is taken out for analysis. An estimate of the lipid content in the samples follows below: • Reindeer meat (estimated to be low to medium contaminated): ≈10 % • Salmon (estimated to be low contaminated): 15-20 % • Fish oil (estimated to be medium to high contaminated): 95-100 % 4. Reporting 4.1 Results to be reported Laboratories are recommended to report as many as possible of the congeners mentioned in chapter 1. The reports should include the determined lipid percent for the samples. The analytical report must include concentrations for all the congeners in all the samples on fresh weight basis, see Report forms B, C, D for PCDD/PCDF and dioxin-like PCBs and Report form 2, 3, 4 for marker PCBs, PBDEs and HBCD. Laboratories must report one concentration on fresh weight basis for each congener which is detected (S/N ≥3), as well as the limit of determination (LOD, S/N =3) for each sample.

Homogeneity testing of test materials for “Interlaboratory Comparison on

Dioxins in Food” organised by the Norwegian Institute of Public Health

Introduction

The International Harmonized Protocol for the Proficiency Testing of Analytical Chemistry

Laboratories (Pure Appl Chem 2006;78:145-96) states that “The bulk material prepared for

the proficiency test must be sufficient homogeneous and stable, in respect of each analyte, to

ensure that all laboratories receive distribution units that do not differ to any consequential

degree in mean analyte concentration. The scheme provider must clearly state the procedure

used to establish the homogeneity of the test material”.

The protocol requires that the variation in composition among the distributed units is

negligible in relation to variation introduced by the measurements conducted by the

participants of the proficiency test (PT). The estimated variation between the samples (ssam)

should be less than 30 % of the target standard deviation (σp), i.e., ssam < 0.3 σp.

Further the protocol states that homogeneity testing is required to reassure the participants in

proficiency testing schemes that the distributed units of the test material are sufficiently

similar. The test specified calls for the selection of ten or more units at random after the

putative homogenized material has been split and packaged into discrete samples for

distribution. The material from each sample is then analyzed in duplicate, under randomized

repeatability conditions (that is, all in one run) using a method with sufficient analytical

precision. The value of σsam is then estimated from the mean squares after one-way analysis of variance (ANOVA).

The quality of the analytical method used for homogenity testing has a large impact on the results. If the analytical precision (σan) of the homogeneity test is not small, important sampling variation may be obscured by analytical variation. We may get a non-significant

result when testing for heterogeneity, not because it is not present, but the test has no power

to detect it. It is recommended that the analytical (repeatability) precision of the method used

in the

homogeneity test should satisfy σan < 0.5 σp

Consequences for the Interlaboratory Comparison on Dioxins in Food

Below follows the consequences for the Interlaboratory Comparison on Dioxin in Food;

1.

The protocol recommends duplicate analysis of at least 10 distribution units. Due to limited

amount of test material in each distribution unit and the requirement for sufficiently low

analytical standard deviation, the test analysis has to be restricted to PCB, e.g., 6 indicator

PCB or CB-153. It is, however, questionable whether analysis of indicator PCB also reflects

the distribution of dioxins and other contaminants in the sample, as the test material is often

prepared by mixing specifically contaminated material with background contaminated

material in order to achieve a sufficient contamination level. Therefore, the distribution of

PCBs in the sample might not be relevant for the distribution of dioxins in the sample.

The analytical precision of the method used in the homogeneity test should be less than half

of the target standard deviation, i.e., σan < 0.5 σp. For determination of dioxins, the target standard deviation may be approximated by the requirement for trueness (Commission

Regulation (EC) No 1883/2006) of ± 20 % for total TEQ, i.e., the analytical precision should

be less than 10 %. This is unrealistic to achieve for the determination of dioxins.

Page 52: Interlaboratory Comparison on POPs in Food - fhi.no · Interlaboratory Comparison on POPs in Food 2018 • The Norwegian Institute of Public Health 2 Published by Norwegian Institute

2.

The homogeneity testing using, e.g., the determination of indicator PCBs, requires the

analysis of at least 60 samples prior to shipment of the distribution units to the participants.

This causes problems for the time schedule of the sample preparation and involves high costs.

3.

The laboratory conducting the homogeneity test on PT analytes would have access to the test

material and knowledge of contamination levels prior to the start of the PT and would

therefore not be qualified for participation in the PT.

Conclusion

A valid testing of homogeneity of the test materials of the Interlaboratory Comparison (ILC)

on Dioxins in Food with respect to the distribution of dioxins and dioxin-like PCBs is not

guaranteed using indicator PCBs. It is doubtful that the analytical precision is small enough to

detect a lack in sufficient homogeneity. Given the need for annually testing three different

matrices for homogeneity, alternative, rapid and low cost homogeneity tests using surrogate

should be applied.

Present approach for homogeneity testing for the ILC on Dioxins in Food

The Harmonized Protocol states under Chapter Testing for sufficient homogeneity: “Tests for

sufficient homogeneity are in practice never wholly satisfactory… However, given that

sufficient homogeneity is a reasonable prior assumption (because proficiency testing scheme

providers do their best to ensure it), and that the cost [and time-consumption] of testing for it

is often high, it is sensible to make the main emphasis the avoidance of “Type 1 errors” (that

is, false rejection of a satisfactory material).

Having this in mind and the facts that it is impossible to determine all analytes for

homogeneity testing of food test material and that a single indicator analyte not necessarily

reflects the distribution of the other analytes, we have developed an approach that ensures that

the test material is thoroughly blended and evenly distributed among the individual test

bottles. The homogeneity testing of solid samples is based on the principle of measuring

electrolytic conductivity after addition of sodium chloride to a small portion of the coarsely

blended test material. A demonstration of homogeneous distribution of the added salt in the

sub samples would indicate our ability to evenly blend the food matrix, i.e., with this

approach we ensure the efficiency of our blending procedure. This is especially of importance

when blending highly contaminated food matrices with background contaminated food

matrices.

When testing homogeneity of the food samples, sodium chloride was added to about 10% of

the test material in such an amount that the conductivity was about doubled compared to the

natural conductivity. This sub-sample was added to the total sample. For example, to 1 kg of

homogenised chicken meat, 150 g NaCl were added resulting in an addition of 1 % NaCl to the final test material of 15 kg. Conductivity measurements are performed as follows: boiling

water is added to 10.0 g of the test material, and the resulting dispersion is ultrasonicated. After centrifugation, the extract is filtered through folded paper filters and allowed to cool to

room temperature. The electrolytic conductivity of the water extract is measured using a

conductivity meter.

Page 53: Interlaboratory Comparison on POPs in Food - fhi.no · Interlaboratory Comparison on POPs in Food 2018 • The Norwegian Institute of Public Health 2 Published by Norwegian Institute

Homogeneity of the test material was demonstrated by comparing the conductivity in water

extracts of 10 samples from the same bottle (variation within bottles), and in extracts from 10

different bottles (variation between bottles).

Example

As an example, the relative standard deviation (RSD) of 10 conductivity measurements within

a sample bottle containing chicken meat homogenate was 2 %. The RSD for the measurement

of samples from 10 different, randomly selected bottles was 3 %. The contribution of the

inhomogeneity to the total variation, calculated from RSD2

inhomogeneity = RSD2

between –

RSD2within

1 was 2.2 % and hence small and acceptable. The total uncertainty for the

determination of PCDD/Fs is usually considerably larger, so the measured contribution of

inhomogeneity to the total uncertainty can be neglected

Appendix 1: Presentation of results: Analyte solution

Statistic calculations for PCDDs, PCDFs, dioxin-like PCBs, indicator PCBs, PBDEs and α-HBCD

The analyte solution contained

� PCDDs/PCDFs at concentrations of 2:5:10 pg/µl for tetra:penta-hexa-hepta:octa

chlorinated dibenzodioxins/furans respectively.

� Non-ortho PCBs at concentration of 10 pg/µl.

� Mono-ortho PCBs and indicator PCBs at concentration of 100 pg/µl.

� PBDE at a concentration of 25 pg/µl, except BDE-209 at 100 pg/µl.

� α-HBCD at a concentration of 500 pg/µl.

These concentrations are called the congeners' target value.

For each congener, the outliers were removed and the consensus calculated according to the

following procedure:

1. The median was calculated from all the reported data.

2. Values outside a range of 50 % to 150 % of this median, were defined as outliers and

removed from the data set.

3. Median, mean and standard deviation were re-calculated from the remaining data. This

median and mean were called consensus median and mean.

The diagram shows the target value and the reported data. Values outside a range of 50 % to

150 % of “median of all values”, were defined as outliers and are not shown in the plot.

Z-Scores of individual congeners

Z-scores of each congener were calculated for each laboratory according to the following

equation:

z = (x – X)/σσσσ

Where x = reported value; X = assigned value (consensus); σ = target value for standard

deviation. A σ of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a

deviation of ± 20% from the consensus value.

Statistic calculations for PCDDs, PCDFs and dioxin-like PCBs

For each congener, the outliers were removed and the consensus calculated according to the following procedure: 1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners.2. Values exceeding 2 this median were defined as outliers and removed from the data set.3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

Statistic calculations for indicator PCBs, PBDEs and HBCD

For each congener, the outliers were removed and the consensus calculated according to the following procedure: 1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners (NDs).2. Values exceeding 2 this median were defined as outliers and removed from the data set.

The NDs were also removed.3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.4. For comparison, median, mean and standard deviation were also calculated without

removing NDs.

The diagram shows the reported data up to approximately the limit for outliers (2 the first median).

Z-Scores of individual congeners

Z-scores of each congener were calculated for each laboratory according to the followingequation:

z = (x – X)/ where x = reported value; X = assigned value (consensus); = target value for standard deviation. A of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a deviation of ± 20% from the consensus value.

Statistic calculations for PCDDs, PCDFs and dioxin-like PCBs

For each congener, the outliers were removed and the consensus calculated according to the following procedure: 1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners.2. Values exceeding 2 this median were defined as outliers and removed from the data set.3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

Statistic calculations for indicator PCBs, PBDEs and HBCD

For each congener, the outliers were removed and the consensus calculated according to the following procedure: 1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners (NDs).2. Values exceeding 2 this median were defined as outliers and removed from the data set.

The NDs were also removed.3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.4. For comparison, median, mean and standard deviation were also calculated without

removing NDs.

The diagram shows the reported data up to approximately the limit for outliers (2 the first median).

Z-Scores of individual congeners

Z-scores of each congener were calculated for each laboratory according to the followingequation:

z = (x – X)/ where x = reported value; X = assigned value (consensus); = target value for standard deviation. A of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a deviation of ± 20% from the consensus value.

Appendix 4: Presentation of results: Fish oil-2018

Statistic calculations for PCDDs, PCDFs and dioxin-like PCBs

For each congener, the outliers were removed and the consensus calculated according to the following procedure: 1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners.2. Values exceeding 2 this median were defined as outliers and removed from the data set.3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.

Statistic calculations for indicator PCBs, PBDEs and HBCD

For each congener, the outliers were removed and the consensus calculated according to the following procedure: 1. The median was calculated from all the reported data, using the detection limit as

concentration for non-detected congeners (NDs).2. Values exceeding 2 this median were defined as outliers and removed from the data set.

The NDs were also removed.3. Median, mean and standard deviation were re-calculated from the remaining data. This

second median was called consensus.4. For comparison, median, mean and standard deviation were also calculated without

removing NDs.

The diagram shows the reported data up to approximately the limit for outliers (2 the first median).

Z-Scores of individual congeners

Z-scores of each congener were calculated for each laboratory according to the followingequation:

z = (x – X)/ where x = reported value; X = assigned value (consensus); = target value for standard deviation. A of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a deviation of ± 20% from the consensus value.
